To all whoin it mayfconoem."V

Be itv knownv that I, MARTIN `L,..B oYD, a citizen of the United States, residing at Zelzah. in the county of Los Angeles, State of California, have inventednew' anduseful` Improvements in Bean-Harvesters, of which f the following -is a specification. f .n

This invention relates to a bean harvester.

It is the object of this invention to pro'- vide a machine for harvesting beans by means of which fthe bean stalks are'severed and stacked, and by which the stacks may be formed'at intervals rearward of the ma.- chine during its progress by delivering the stalks rearward thereof, andv which is so constructed that after the machine has traversed one row and is returned on an adja- Another object is to provide means for shifting the hopper into any desired position within its range of movement, and to provide mechanical means for automatically' discharging the hopper 1n any of its positions.

A further object is to provide means' for automatically discharging the hopper at predetermined distances of travel ofthe harvester.

The invention is illustrated inthe accompanying drawing, in which:

`Application ied February 3, 1915. Serial No. 5,880.-

' nism.- Fig. 7 isf adema. inf-pian iiiustmung the mechanism `for,swingingthe stacking hopper' v 'T n A y Moreispecifically, A10l .indicaties` the frame ofthe harvester whichis mounted on any suitable running gear, here shown as consisting of apa-ir of forward wheels 11 and 12 and rea-rj wheels 4v13 andzll.: 'The -frame 10 isformedwitha'downwardly extending portion carryinga pair'of horizontallyextending. diagonally-arranged cutting blades 15 and* 16 which converge toward each other,

' and are adapted' to sever the'stalks ofv aphi-` -rality of rows .ofbeans yas the harvester is advanced. The` frame 10 is formed with a horizontally-extending rigidiportion 17 arranged above-the wheels l13-and 14 and eX- tending rearwardly thereof.

vPivotallv mountedon'the rigid frame as particularly shown in Fig.` 2 is a swinging frame'18 which carries a horizontallyextending conveyer belt 19, supported onsuitable rolls or sprockets 20 and 21, carried by the swinging frame 18. Secured to the outer end of the swinging frame 18 and depending therefrom is a hopper 22, into which the stalks delivered to the belt 19 are discharged the stalks being delivered to the belt 19 by means of a pair of conveyer belts 23 and 24, carried on "suitable rollsmounted on the frame 10 and'extending upwardly from the rear ends of the cutting blades 15 and 16, with .the upper end of the beltv24 terminating above the belt 19 at such point as to discharge on 'the belt 19 irrespective of the position of the swinging frame .18.

The hopper 22 is provided with a drop closure 25, hinged'at 26 to ,swing downwardly, andhaving a rearwardly extending arm 27, which is connected byl a link 28, to a crank 29, on f'a shaft 30. carried in a bearing 31 supported on the hopper v22.

40 groove 62, formed on a disk 63, on a shaft sprocket chain 41, which passesl around :sprocket wheel 42, mounted on a clutch shaft 43. carried on the frame 10, and the clutch shaft 43 is fitted with a sprocket wheel 44, engaged by a sprocketchain 45, passing around a sprocket wheel 46 attached tothe wheel 214,' and 13 ofthe harvester y running gear.-

. such shaft is rotating.

f of a clutch sleeve 58, Vreciprocally mountedon the shaft 37 intermediate the hubs 55 and clutch sleeve 58 being adapted to be posi- Looselymounted on the shaft 37 is a gear 47 ,which meshes with apinion48, connecting with-the sprocket wheel 49 to a short shaft 50, mounted in a bearing 51, carried l l byP a bracket 52, attached at one end to the hopper 22 and pivotally connected to the shaft 37 at its opposite end. The' sprocket Wheel 49 engages a sprocket chain 53, which extends upwardlyy and passes around a sprocket wheel 54, on the roll 20, in such manner that theconveyer' belt' 19 will be rotated on rotation ofl the gear 47 when the latteris clutched kto the shaft 37 and while The gears 36 and 47 are formed with 'hubs 55 and 56 respectively, which extend toward each other, and have clutch teeth 57 formed on their ends adapted to be engaged by corresponding teeth formed on the ends 56, as particularly shown in'Fig. 2; the

tioned out of engagement with either of the gears 36 and 47 or to be alternately en gaged therewith. The clutch sleeve 58 is 'normally held in engagement with the gear 47 .by means ofk a lever59, which pivotally connects therewith and is pivoted at160, on

a hanger 61, carried by the stationary, hor-v izontally extending frame 17. The outer end of the lever 59 is'engaged by a cam 64, carried in suitable bearings supported on a rigid portion of the frame 17. The shaft 64 is provided with a pinion 65 which connects with a sprocket wheel 66, to a short shaft 66a; thesprocket wheel 66 being normally engaged by the `sprocket chain 41. The gear 36 is normally held against rotation while the clutch sleeve 58 is out of engagement therewith by means of a spring pressed locking pawl 67, pivotedy at 68 on a i rigid portion of the frame 10; the pawl 67 having an upstanding ear 69 provided with a cam face adapted to be engaged by a lug orprojection 70 on the clutch sleeve 58 to force pawl 67 out of engagement with ratchet teeth 67 on hub55, as the latter is advanced into engagement with the gear 36. The sprocket chain 41 serves as a driver for the'conveyer4 belts-23 and 24, and for that purpose is directed around sprocket ywheels 7 5' and 76 and in operative engagement with sprocket wheel 76a on the rolls, around which the upper portions of the, conveyer belts 23 and 24 pass.

As a means for swinging the pivotedf frame 18. the latter is here shown as pro vided with a pair of ,cables 77 and 78, which are secured to the opposite lsides of the pivotal point 79 of the swinging frame 18,

and extend forwardly around the edges of:r

the conveyer beltsv23 and 124, and are'secured to the opposite sides of a segment 791, l

pivoted on a rigid portion of the frame 10 at a point near the operators seat 80. The segment 79 is fitted with a handcrank 81,=

carrying a locking pawl 82-adapted to en-,Y gage sprockets or teeth 83. ona fixed seg# ment '84,- whereby thepivoted segment may be-locked tohold the swinging frame 18 and tion;` As such are extensively the specific construction thereof isfnota feature of my invention, thedetailsthereof locking ports and segments used and lwell known, andi .80 2 the hopper 22.thereon in anydesired zposi=` are not shown in thedrawings. As gears f v35 and 48 are secured to `hopper 22 which:

may be swung: concentric toshaft 37 and mesh respectively'with gears36and '47 ony said shaft, thehopperclosure 25 and 3belt 19 will be operated in `any position iin-r the hopper 22.

In the operation `of theinvention, as the harvester is advanced the beans are severedl by the cutting action lof Vthe bladesl :and 16, whereupon they are engaged by the cony `veyer belts 23 and 24, which are lnoved Ein the direction indicated by the arrow4 a in.

Fig. 1; the conveyer belts 23 'and 24 disf Y charging the beans on to the conveyer belt 19, carried vby the pivoted frame 18. The.

frame 18 is disposed in any desired position,

.according to the point at which` it is in-f tendedfto discharge the bean stalks, being positioned rearwardly of the machine, as, shown in-Figs. 1 and 5, when the stalks are to be stacked behind the machine as it ladvances. beans to one side of thefharvester, the pivoted frame 18 is swung by means of thehandcrank 8l and its connections to the swinging frame to any l position; they frame 18 i turning onlthe pivot 79, with its outer :por-

tion supported ony a segmental track 85carried by the rigid horizontal frame 17.

As the harvester advances the cam :63 is rotated, and during the major portion of its revolution it operates on the lever -59`to maintain the clutch sleeve 58 in engagement `with the gear 47, soy that the latter will re-` volve and drive the conieyer belt 19 on they swinging frame 18; theca'in-groove -62 ont,

When it is desired to stack the-- the cam disk 63 being formed for a greater part of `its length concentric with the shaft;

64: The Wall 86 of cam groove 62 extends inwardly as shown in Fig. 4 `of the draw,n

ings, which yon engagement .with the end of the lever 59, operates `to rock the lever to shift the clutch sleeve58 downwardly and'` into engagement with thegear 36. They llll clutch sleeve 58, on movement into engagement with the gear ,36, operates, through the lug 70, to disengage the locking pawl 67, so that rotation of the gear 36Vwill be effected on engagement vwith the clutch sleeve 58 therewith. The rotation of the gear 36 operates toA drive the gear 32,1

through the shaft 34 and the pinions 33 and 35. Rotation of the gear 32 revolves thev crank 29 and thereby operates, through the link 28 and frame 27, to rock the hopper closure 25'v downwardly to discharge the contents of ,thev hopper therefrom. On the crank 29 and gear 32v making a complete revolution, the hopper closure 25 is rocked to its open and closed position. Immediately upon the closure 25v being restored to its closed position, the cam 63 operates on the arm 59 to withdraw the clutch sleeve 58 out of engagement with thefgear 36. Thelocking' pawl 67 previously' held out of engagement with the teeth on the hub 55, will then be restored intoengagement therewith and will operate to lock the gear 36 against rotation. and thereby7 hold the hopper closure 25 in its closed position until it is again y actuated by the cam 63.

Suitable mechanism may be employed for throwing the various driving parts out of their operative connections with the running gear wheels 13 and 14, as occasion may require, and any desired construction may be i employed for raising and lowering'the'cutting blades 15 and 16 to dispose them out of their operative positions..
